Polyol preparation by liquefaction of technical lignins in crude glycerol
(Scrivener Publishing, 2017)This work reports a study of polyol synthesis through liquefaction of technical lignins in crude glycerol by means of 1H and 31P NMR spectroscopy. The polyols are intended for preparation of polyurethane foam; thus, it is ... -

Production of bio-degradable polyurethane foam from sugarcane bagasse and biodiesel-derived crude glycerine
(ETA-Florence Renewable Energies, 2015)As the threat of the depletion of fossil based fuels becomes more of a reality, there is a need to find alternative carbon sources for the production of a wide range of chemicals, polymers and plastics. One plastic that ... -
Separation of lignin from industrial prehydrolysis liquor using a solid acid catalyst
(ETA-Florence Renewable Energies, 2019)The concept of a biorefinery has been introduced in the pulp and paper industry in order to improve the industry’s profitability and competitiveness by generating new revenues from new products. Prehydrolysis liquor (PHL) ... -
Valorisation of waste lignin for phenol derivative compounds using hydrothermal liquefaction
(EUBCE, 2019)Approximately 95% of global phenolic compounds (such as catechol, guaiacol, syringol, and vanillin) used in the pharmaceutical, fragrance and industrial industries are produced from petroleum-based phenolics such as benzene. ...
